Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Description & Operation
The charging system consists of a generator/regulator assembly, charge indicator, battery, and required circuitry. Charging system uses a mega-fuse (100-amp on 2.3L or 120-amp on 3.0L) to prevent system damage. Solid-state regulator, mounted on rear of generator, is factory-calibrated and cannot be adjusted.
When engine is started, the rotation of the generator creates AC current, which passes through the rectifier assembly, where it is converted to DC current. Generator supplies 13-15 volts to vehicle's electrical system.
